Specification of Letters Patent.

Serial No. 414,577.

T all whom it may concern:

Be it known that I, WHEATLEY YARD, a citizen of the United States, residing at Mayo, in the county of Anne Arundel and State of Maryland, have invented a new and useful Anchor, of which the following is a specification.

This invention relates to anchors and has for its object to provide an anchor in which the stem or shank is free to move laterally with respect to the iiukes when the latter are embedded in the ground so as to prevent dragging of the anchor incident to the pull on the anchor chain as the vessel rides the waves in a rough or choppy sea or is swerved laterally by the action of the wind or tide.

A further object of the invention is to provide an anchor the construction and relative disposition of the several parts of which are such that the heel of the shank forms a fulcrum for the anchor when the latter is weighed thus exerting an upward pull on the flukes and disengaging the same from the ground.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efhciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a front elevation of an anchor constructed in accordance with my invention, the stem or shank of the anchor being shown in full lines in normal position, the dotted line position indicating the movement of the shank relatively to the flukes. Fig. 2 is a view of the lower portion of the shank and its associated parts. Fig. 3 is a side elevation partly in section.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved anchor forming the subject matter of the present invention includes a stem or shank 5 having one end thereof extended laterally at 6 and its opposite end provided with a pivoted loop or shackle 7 for connection with the usual anchor chain or cable. Formed in the thickened portion 6 of the shank is an elongated slot 8, the

walls of which are curved laterally at 9 to accommodate the connecting arm 10 of the flukes 11. Communicating with the slot 8 is a relatively shallow recess 12 in which is seated one end of a link or pin 13 the opposite end of which is provided with a cylindrical head 14 which engages a recess or socket 15 formed in the intermediate portion of the connecting rod 10. The recess 1.5 is some what larger than the head 14 so as to permit free tilting movement of the fluke arm 10 with respect to the shank, there being an enlargement 16 formed on the connecting roe at the recess 15 thereby to reinforce and strengthen said rod at its point of juncture with the lever 13. The lower end of the link 13 is seated in the recess 12 and is pivotally connected with the shank in any suitable manner, as by a pin or rod 17, the lower end of the pin or link 13 being curved or rounded at 18 so as to permit said pin to oscillate freely within the recess. It will thus be seen that the flukes are connected for universal movement relatively to the shank, while the latter is shiftable longitudinally of the fluke arm 10 so as to prevent dragging of the anchor incident to the pull on the anchor chain as the vessel rides the waves in a rough or choppy sea or is swerved laterally by the action of the wind or tide.

As a means for limiting the lateral movement of the shank, suitable segmentalbars 19 are extended transversely across the slot 8 and arranged in the path of movement of the pin or link 13 so that as the shank vibrates on the fluke arm 10 the link will enga e the adjacent bar and form a stop for the s ank. The bars 19 not only serve to limit the lateral movement of the shank but also constitute keepers for the pin or link 18 so as to prevent accidental displacement of the same.

It will here be noted that when the shank is in either of the dotted line positions shown in Fig. 1 of the drawings and the winch or capstan operated to weigh the anchor the lower or heel end 20 of the shank will form a fulcrum for the anchor so that the upward movement of the latter will readily disengage the flukes 11 from the ground. nection that the upward pull or strain is on one side of the center of the fluke arm 10 so as to elevate or disengage one of the flukes from the ground before elevating the other. The flukes 11 may be made in different It will also be noted in this consizes and shapes and in the present instance are shown with terminal lips 21 which bite into the ground and assist in anchoring the same. It will thus be seen that as the vessel tugs or pulls at the anchor chain or cable the flukes 11 remain embedded in the ground while the shank 5 is moved longitudinally of the connecting bar with a relatively rocking movement, this result being accomplished by reason of the universal connection between the shank and flukes.

From the foregoing description it will be seen that there is provided a strong, durable and thoroughly elficient device admirably adapted for the attainment of the ends in view.

Having thus described the invention what is claimed is:

1. An anchor comprising a shank, a fluke arm extending through the shank, and means forming a pivotal connection between the shank and arm for permitting universal movement of said arm relative to the shank.

2. An anchor'comprising a shank, a fluke arm pivotally mounted on the shank and free to swing in a plane at substantially right angles to the length of said shank, and an inde )endent pivotal connection between the shan and fluke arm.

3. An anchor comprising a shank, a fluke arm pivotally mounted on the shank and spaced from one end of the latter, and an independent pivotal connection between the fluke arm and the adjacent end of the shank.

4. An anchor comprising a shank, a fluke arm pivotally mounted on the shank intermediate the opposite ends of the latter, an independent pivotal connection between the fluke arm and one end of the shank, and means for limiting the movement of the shank.

5. An anchor including a shank, a fluke arm pivotally mounted on the shank, and a link disposed in the same plane with the shank and forming a pivotal connection between the shank and said fluke arm.

6. An anchor having a slotted shank, flukes pivotally mounted for tilting movement in the slot, an arm connecting the movable longitudinally of the latter, and

means for limiting the lateral movement of the shank.

9. An anchor including a slotted shank, a fluke arm mounted for tilting movement in the slot, a link forming a pivotal connection between the arm and the adjacent end of the shank, and means extending across the slot and engaging the link for limiting the lateral movement of the shank.

10. An anchor including a shank having a lateral enlargement pierced by an elongated slot terminating short of the lower end of the shank, an arm extending transversely through the slot and provided with flukes, a link having one end thereof pivotally connected with the intermediate portion or" the arm and its opposite end pivotally connected with the adjacent end of the shank, and stops extending across the slot for engagement with the link.

11. An anchor including a shank one end of which constitutes a fulcrum, a fluke arm extending transversely through the shank and mounted for tilting movement thereon, and a pivotal connection between the arm and shank whereby the latter is free to move longitudinally of the arm.

In testimony that I claim the foregoing as 7 my own, I have hereto affixed my signature in the presence of two witnesses.
